US Secretary of State will meet with German Foreign Minister Heiko Maas before they lead a 20-nation virtual meeting of ministers on the way forward in Afghanistan
G7 leaders will also discuss how to improve access for evacuees to Kabul airport, Maas told reporters in Berlin, adding Germany has been looking at options for keeping the airport running beyond Aug 31 for days.
"We will reduce personnel of the German embassy in Kabul in the coming days to the operative absolute minimum," he told reporters. "We will send a crisis support team to Kabul to help us boost security precautions" during the evacuation.
Iran retaliated by violating the limits imposed under the accord on its nuclear programme. It now seeks an end to United States sanctions.
Under JCPOA, Iran limited its nuclear program to make it harder to obtain fissile material for atomic weapons in return for relief from US, EU and UN sanctions.
"Our message remains clear: We are prepared for dialogue, and we have made proposals, but the key to a better relationship lies clearly with Moscow," German Foreign Minister Heiko Maas told reporters before a video call with his NATO counterparts.
"We are there to prevent conflict and war. But the best way of doing that is to send a clear message to any potential adversary that if one ally is attacked, the whole alliance will be there," Stoltenberg said.
Talks will mainly focus on preparations for national elections planned for December 24 as well as the withdrawal of foreign troops and mercenaries from Libya.
